我有一个中继器，当数据数量增加时，会显示滚动条。当我单击中继器内的任何行时，它会被选中，并在下一个 div 中相应地显示数据。假设我单击最后一条记录，显示数据并且行也突出显示，但滚动到它的初始位置而不是最后一个。

protected void Page_Load(object sender, EventArgs e) { ScrolBar();}

private void ScrolBar()
{
    HiddenField PosX = new HiddenField();
    HiddenField PosY = new HiddenField();

    HtmlControl Form1 = this.Master.FindControl("Form1") as HtmlControl;
    PosX.ID = "PosX";
    PosY.ID = "PosY";
    Form1.Controls.Add(PosX);
    Form1.Controls.Add(PosY);

    string script;
    script = "window.document.getElementById('" + PosX.ClientID + "').value = "
              + "window.document.getElementById('" + test1.ClientID + "').scrollLeft;"
              + "window.document.getElementById('" + PosY.ClientID + "').value = "
              + "window.document.getElementById('" + test1.ClientID + "').scrollTop;";

    this.ClientScript.RegisterOnSubmitStatement(this.GetType(), "SavePanelScroll", script);

    if (IsPostBack)
    {
        script = "window.document.getElementById('" + test1.ClientID + "').scrollLeft = "
                + "window.document.getElementById('" + PosX.ClientID + "').value;"

                + "window.document.getElementById('" + PosY.ClientID + "').value;";

        this.ClientScript.RegisterStartupScript(this.GetType(), "SetPanelScroll", script, true);
    }

只需将以下内容放入Page_Load：

this.Page.MaintainScrollPositionOnPostBack = True

Page.MaintainScrollPositionOnPostBack 属性

对于 Repeater 或 GridView 试试这个：Put control inside div and add an option OnSorting

<div id="divGridView" runat="server" >
    <asp:GridView ID="Grid" runat="server"  OnSorting="Grid_OnSorting"
                OnDataBound="Grid_DataBound" >

在代码文件上添加此方法：

protected void Grid_OnSorting(object sender, EventArgs e)
{
   divGridView.Page.SetFocus(Grid);        
}
